Suggestions for Honneymoon.

Hello, my fiance and I are getting married in November 2012 and are looking for a place to go on a honeymoon. After getting numerous quotes from travel agents I have been able to narrow down my choices to the following. We have never been out of the US and would really like to go somewhere with a nice beach and would like to go snorkeling. We would also like for there to be entertainment available as well. We aren't too picky just would like to stay somewhere very nice. Thanks!
